If you have a Rigid Industries 50" E-Series led light bar, or a SR-Series LED light bar, this mount kit is perfect for you. This windshield mount works on the 50" light bars and use the mount points that already exist in the A-pillars. You don't have to drill or cut anything new. The brackets in the kit are made from high strength steel and are coated to match the light bar so they blend right in. You get rubber gaskets as well to prevent paint damage. Keep in mind that you will need longer hardware that is not supplied if you want A-Pillar Dually D2 lighting and mounting kits.
